Stop caring about what other people think. They don't matter

Achieving goals, both big and small.

Best way to do it is to do things that [i]you[/i] feel improve [i]you[/i] !

Could be anything !
You choose !

If you find that difficult, here's what i do.

When the alarm goes off, get up ! - It's a sign of intent !
Make your bed. ! - If all else fails and you have the sh*tt*est day. At least when you come home, your bed is made ! - And YOU made it !
When you hit the shower and get dressed, shave well and style your hair ! - Even if it means nothing to you, Other people notice this stuff ! - It makes them think you have confidence in you !
Eat breakfast ! Sounds simple. But you'll feel better just for having eaten before your day starts !
Polish your shoes ! Odd as it sounds the number of comments i get about that aspect of my appearance is ......odd ! But again, it shows intent !

Little things like these make a difference.

Misanthropy works

Develop and value your strengths in a few areas so you can have a solid core of self-worth to fall back on when you fail with something else.

I think the first step is finding a hobby or skill they can be proud of and shine in. Finding something they can find self validation in as opposed to external validation is important.
