I would add to this the following. You are the person you spend the most time around. You have power to affect your own outlook in small ways on a day to day basis. Added up over a long period of time can result in real change in outlook. I'm talking really tiny things like instead of saying "I'm bad at X" say "I haven't done X well before". Sort of brainwashing yourself into a growth mindset.
