It's so bad for one to have a very lucrative skills and yet not making good use of it, I think such person isn't ready for the life meanwhile skills is the most valued and we'll paid criteria we have in the world today so if you ain't making good use of it, I wonder the reason for achieving such skills. And being a jack of all trades has so much of benefits such that you can be called to work anywhere and paid your services without stress. So it's something everyone should take seriously by owning a skill and making good use of it.
A very simple question why someone who has skills cannot support utilization in finding jobs that are more suitable to be lived by him, isn't this kind of person much easier to get a job. The assumption may be found in a bad lifestyle such as lazy and too choosing a job so that the skills they have are even more difficult to get a job. This often happens because most people choose jobs instead of carrying out their hearts work that exist in order to get money to support their lives with family.
Except for people who are ready to build their own business, taking the risk of leaving the job they have are not a problem, as long as they consider the impact. In life sometimes does not go according to expectations but we need to prepare ourselves with all the possibilities that will occur.
