Really good advice

Don't do it.
Don't step out of your comfort zone.
Don't  learn new things.
Don't change your mind.
Don't volunteer to change the world.
Don't smile or make an offer to help someone who can't help you back.
Don't invest unless there is a guaranteed outcome.
Don't question authority.
Don't worry about the problems on the other side of the world.
Don't take a chance.
Don't try.

Leave that hard stuff for someone else who is 
better than you,
richer than you,
smarter than you.

They've got it covered- right?
