Is competition healthy for your well being?
Yes. Yes it is.
Who do I compete against then?
Yourself.
The road to getting better at anything doesn't involve you competing against other people. Imagine - you were the best at your craft. How would you get better?
Compete against yourself.
Fight yourself tooth and nail. Trade blows. See who's got the keener eye for the situation. Better yourself tomorrow, or the next day.
Compete against yourself.
You'd be amazed at the results of such a thing. Don't fall into the trap of competing against other people. It's a deep and dark rabbit hole friend.
Compete against yourself.
