It's a real quandary.
I know people who have completed modular and integrated training and have walked straight into jobs. I also know people who have completed training many years ago and have not yet found anything. There are also people who have spent at least 4 or 5 years full time instructing before moving on.
It all comes down to your perception of risk and benefits vs expenditure.
When you read posts on here saying it's no different to paying for a legal or medical degree and working on reduced benefits / remuneration as a junior doctor or lawyer, I'm sorry but that is absolute rubbish. At the end of the day Pilot licenses are not as transferable to other jobs as a medical or law degree is for example. Therefore you have spent £50-£100k on a very particular and specialised career path.
Again, the other posts you will see are along the lines of well you don't want to reach 75 and think if only. This mantra is a total waste of time. The decision to commence a flying career should be made with the brain only and emotion shouldn't come into it. It's the same as somebody saying "live every day like it's your last", not realistic as nobody would want to visit the post office or cut their toenails if it was their last day, but sometimes these things must be done. Anyway I digress!
