"When you stop competing you start creating. Never compare yourself or your life to others - anything they have that you desire, you can have too."
Best advise I have ever taken in my life.
When I first started my photography business nearly 4 years ago I was so caught up in what everyone else was doing, how they were doing it and how much better than me they all were. Well duh, you just started a business Stine, of course they are better than you!
It is such a natural human thing to do, to compare and criticise every little thing you do. Nit pick everything apart and end up too paralysed to take any action let alone CREATE anything of value to anyone else. If you are caught in this, STOP RIGHT NOW!
Good, now breathe and go create that life you always dreamed of.
