Some things that have been difficult is learning to be critical of my work, I need to know when my work or ideas stink and having the discpline to work when I need to and play sometime as well.
But.....the biggest bumber of all is that, just like in retail work, just because you are there doing your thing, people will not always come.
Internet Marketing is by far the most challenging and exciting thing one might hope to pursue. The very best things are being able to work when I feel motivated, like now at 4:30 am.
