I'd suggest that sitting a GAPAN aptitude test is invaluable, before you start parting with the hard-earned cash. This will give you an indication of whether you're mentally suited to be a pilot, and the Class 1 medical indicates whether it's physically viable to pursue it.
These are 2 pretty good criteria to use to base your judgement on.
A healthy dose of optimism that it will all work out in the end & you'll get a job is another.
