My good porpuse monthly

Hi, thank's goodness it's friday!
eventhough I've finished(had finished) my holiday nearly one month ago and I'm already completely empty, without of energy.
I'm not too old enought so, probably, I wasn't made for work!  (I am not man of work)
I worked as manager, for 8 years in my other life  past; I was a CTO for a public company.
It was hard enought ...
I thought it could be better for my for the quality of my life, to change my job. What is better than became a freelance?: you're "free" to work whenever you want .... and it's true.
But why do I work for 10 hours a day?
I must to explain my problem to my boss ... Ops, the boss it's me.
By the way, today the games are over: all of my free time will be dedicate to read, write and (try to) chat in English.
Please, help me!!
