Boys.
I have a boy and a girl. My son... is just SO much more physical and active. Boys, are just more kinesthetic.
And yes, yours sounds spirited.
For any child, really cue into him and "see" what he 'needs' and really tune into him. As you said, he really seems to need to get outdoors. And he is very curious (as most kids are) and he is cerebrally active as well as physical. He seems well developed. That is good!
I know it's then, 'tiring' or not easy for the Mom with a boy like this. My friends who have boys, go through the same thing. :)
For me, what works is I taught my son from a young age: (1) the word "danger." (2) I taught both my kids sign language. Which comes in REAL handy when your child is across the other side of the room and instead of sprinting across to them or 'yelling' to them... you simply say their name then use a sign language cue to "tell" them what is "no, no" or "stop" or other things. It is real handy with an active boy! I do this with my son and it's great. Just by my using certain hand signs for "stop" or "come" or "quiet" I can convey to him something without raising my voice or stopping him in a moments notice if he is scampering away. (3) use your words... and with repetition, he will 'learn' various words and what is appropriate or not.
BUT, through it all, know that at this age and through 3 years old, they do NOT have full impulse control, nor attention spans. So... this is the way it is.
Meanwhile, just make sure your home is safety-proofed. Any bookshelves for example, can fall over and pin your son under it, hurting him or worse. So make extra sure, that with your active boy, you make everything safe!
Boys LOVE to climb... and they climb anything- shelves, jalousie windows, tables, counters, beds, ladders, stools, sofas, anything! And they also like to "jump/dive" off of things too. My son once opened a drawer to my Mom's credenza... and then he used the drawer to climb onto it... and it toppled over! SCARY! Luckily it did not crush him... as this was a VERY VERY heavy credenza and none of us thought it could topple over. But it did. We have since put it away.
And yes, kids ALWAYS want something they can't have. Such is the nature of a baby/toddler. So you need to distract him. If he yells... don't worry, a child WILL de-escalate on their own, even though it is not pleasant to hear. But guide him with your actions and verbally... even if it seems to go on deaf ears. They do catch on, sooner or later. Its all about "repetition." That's how they learn.
ALso keeping in mind their cognitive development PER their age. A 14 month old is just not going to understand wordy rationalizations or explanations. And then sometimes, even if they tantrum/yell because they want something... just repeat calmly "no... " or "not now..." or "stop..." etc. And then wait, and they will still yell/tantrum. But once they know you are not going to rush around to appease them with a "treat" they will stop. But again, they at this age, do NOT have full control of their impulses, much less emotions. So keep that in mind.
But mostly, do not expect him to do, what is "older" than he is. Things have to be age appropriate... including, expectations upon him. Or, both of you will be continuously frustrated. As it is already happening. At 14 months old....a child will NOT act all 'organized' and only keeping to "their" cabinet. Do not expect that, or you will always be disappointed in him. EVEN a Preschooler will NOT always do this either. So try and keep this in perspective, if it helps. Even my 6 year old child does this... and wants other things from elsewhere and not only "HER" drawer. They are kids. They cannot YET manage themselves. That's why we help them. It takes an entire childhood to learn the basics... even Teens too.
Try and join kids groups, Gymboree, play/parent groups etc. Get his yah-yah's out.... kids need this. They go stir crazy too.
Oh, also maybe try and watch what you feed him... go easy on juices (ie: sugar) or other things. For some kids, this just throws them into a tizzy or they get fussy.
All the best,
Susan
