It is worth starting mining if you will think that electricity cost is not a problem in your place. But if does, I would say that to take a look for another option where to put your money.

Mining is not an easy game,
 - huge expenses (electricity)
 - needs a high level of mining machine to become competitive
Everything is expensive and with the huge competition, I don't think it was worth it to start with.
Many people had stop because of those things but of course, I was not good enough to judge you. Why not if you think you can do it.
