I see you're in Manchester. You are well placed! Go along to Lancashire Aeroclub Flying School at Barton (now called City Airport) and fly with the CFI, Martin Rushbrooke. He will kindle any enthusiasm you have and get you set on course for your licence. He will give you realistic advice on time and costs etc.
I did my PPL at LAC back in 1978 and flew from Barton for many years. Martin taught me aerobatics in our Chippy, and did my conversion onto the Yak52.
You cannot possibly do better than a session with him!
