Hi Paul,
One thing I have learned it not to compare myself with anyone else. If I did I would consider myself an unqualified disaster!
This is why I suggested setting targets you alone would be happy with. They may (or may not) fall short of the expectations of others, and as everyone's circumstances and needs differ, comparisons don't really matter anyway.
You have been in this game for nearly a year. Are you making a living from the work you have built up so far? If you are, then you are doing really well and have a good basis on which to build. If you are not quite there yet then don't worry, keep on plugging away and you will get there.
Only you know how much you need to earn. Once you have achieved that, any extra is a bonus. Once you get there, you will find that work will come to you more readily and your confidence (and your business) will grow.
Best wishes,
John
