I used to know of several people who were once in your position. Some gave up (I don't think you will!), most got their licences - eventually and others tried other forms of aviation. But most interestingly (for me) was that of those who actually got their licences, they gave up shortly afterwards as well. What they hadn't done is work out what they wanted from flying. May I suggest that you work that out first. The PPL is the ticket to enable you to fly, not the reason. The activities available include touring, rallying, aerobatics, racing, vintage, tail-dragging, photography etc. For myself, I got a PPL to expand my gliding knowledge (weird I know!) and ended up tugging. If you work that out, then you will know whether your investment will be worthwhile.
Best of Luck.
