I have been in the business 27 years. I don't mind spending a buck to make a bunch of bucks.
Not bragging, but I do have a few years on you, and I do agree the adage you have to invest money to make money is still true.
I discovered early on in my career that I am a marginal prospector (but have improved dramatically over the years) and it is something I still hate to do.
My time is value and my skills are best put to use solving problems for clients than kicking tires trying to find fresh meat.
I would much rather go to the store and buy my steak rather than going out, tracking something down, killing it, then dressing it so I don't starve.
