Becoming a pilot is not that easy, an happy one is even more difficult.
The secret of success doesn't hide in the fact of having 24 or 29 years old.
Age is not a problem, especially 29, you are young. you still have more than 40 years to work. Question shouldn't be about age. It should be about the viability or not to be a pilot for the next 40 years... And here I can see an issue...
