"Take some time and think about what you will give up(Job Security) And what will you gain (Possibly 50~60K maybe more) "
IMO the only true job security is self-employment, esp the lawncare and related industrys. Trends in this business are such that you can tell which aspects are waning and which are on the upswing and adjust your market focus accordingly.
Working for the man, well, there are no promises, you could show up tomorrow and find a chain on the main gate, then what?
Yesterday is a memory. Tomorrow is a mystery. Right now is your reality.
