Career choice

I want to change my career and I am torn between two different choices.
Choice 1. Pursue corporate career in software sales
Choice 2. Become an entrepreneur – life coach
The problem is that I like the second choice better but the first choice is more believable in terms of success achievement.
I believe that there is a better chance that I will achieve professional and financial success in Tech sales rather than as a life coach. I believe in the power of coaching though, I just don’t believe in my entrepreneurial abilities.
If I think about it there is also a third choice of doing both things. It feels like the most sound solution but I am afraid that I will do both only half way and succeed in neither.
My model is:
C Desire to change career ( currently unemployed)
T I must make a choice and start taking action
F indecisive
A Not taking action
R Feeling stuck
