Thank you all for the replies.

Gary, to learn 1 new song every week is my goal, but honestly, it is hard to me because it's not my main job. It's a hobby first, but I am so impressioned by that technology that I would like to play out sometimes.

mdoranes, 600 songs!! It will take 20 years to me to learn so much songs. Congratulations.

Scott, to the genesys, DonM, Thanks for your encouraging words.
In fact I will consider myself ready to start when I will be able to play 70 to 80 songs (an entire gig without play the same song twice).
I have now +/- 35 songs.
But the way seems to be sooo loooong!
Ther is also the fact that I play alone.
Don't you feel sometimes tired to play alone? I mean psychologicaly!
