Am I selfish?

[Cysne]

Hello all, thanks for ready.

It's a question that's floating around my head, I'm 20 and have been saving money since I started working, by the time I hit my 21st birthday, I should have around £15k ready (+5k worth of car to sell). (Yes I've lived like a hermit)

I've just come out a long relationship due to my wish for a big trip, I've been given a good chance for a very good job for my age from my father (Which i've excelled at and now got the full time gig) but all I have at the back of my head, all I want is April next year is to just go, escape do my trip. Get on my bike and just go.

However, I just feel really selfish, to my parents, they've gave me much, it's not just the feeling of selfishness. I feel like i'm going to disappointing a hell of alot of people doing a trip like this.

The thing is, I know it's what I want to do, i've saved for ages, cut out things out of my life and do 12 hour days at work atleast 4 days a week. I don't really enjoy other things, just this focus, fixation.

Should I just hit on the road and hope people come round to the idea?

It feels like im between a rock and a hard place. How do I get round this feeling?

Any ideas, opinions, or your own experiances. Please.

Ps, yes I did post about it around a year ago, but I tried ''real life'' however, it sucks.
