There is no “perfect” time/timeline for certain goals to happen.
Everyone’s journey is different.
For example, a lot of people think 27–30 is “the” age when people should start to seriously date and look for a long-term relationship.
Serious relationships can happen at anytime — 18, 22, 25 30, 35, 40. There’s no set timing for anything.
I think it’s a bad idea to think certain years for certain personal/professional goals.
Go at whatever timeline you desire.
Everyone’s life journey is different.
