Five willies here!!
I've been flying for 20 years, 13 commercially and I still absolutely love it. Always look forward to going to work (long and short haul) and always have a good time - even on hard days. Outside of work I still instruct and love that too.
There are ups and downs - take them in your stride. Once you are established in the job make sure you join the fight to protect/improve T's and C's.
I say go for it sleepyrascal and the very best of luck to you :-)
