If you can afford it you should go for it. I did, never got a job but count passing my IR first time (and to a lesser extent CPL) as one of the best achievements in my life and I enjoyed every minute of it.
Warning: before you get into a Seneca you have to do groundschool and that feels like a bit of a waste of time to be honest.You are studying whilst the sun is shining and life is passing you by.
If you are unsure about it maybe just do your PPL and buy a nice aircraft instead.
