Within reason, here is what I suggest....
learn to cook so you save money. Avoid eating out too much and developing that habit.
exercise
Dont drink alcohol nor smoke.
develop your executive skills for work and social. This is on top of any technical skills required for your career
Save money, park as much as possible into your 401/IRA.
Contribute to the community.
Live close to work so you do not spend all your time commuting.
Its okay to pick up cheap things at the thrift store.
Never get a storage locker.
I guess if you have a fragile ming vase, a storage locker is ok. But, it may be worth having things stolen if it avoids reoccurring storage fees for things of little value or things that depreciate in value.
My last line of my post may have been a little snarky, having spent all day in a twisty maze of storage lockers all alike.
