Focus on yourself.
Focus on being the best version of yourself.
If you always compare yourself to others, you will never be happy.
I have to battle this ALL. THE. TIME.
That person is more successful
That person is younger and has done more.
That person is making more money.
There is always going to be THAT person.
But you know what.
You have to focus on yourself if you ever want to be THAT person.
Compare yourself to where you were X days/years ago.
Focus on yourself day in and day out and all of a sudden you know longer think about 'that person'
Because they don't matter.
