What advice would you give to your younger self?

This may be more appropriate for the older members, but younger ones may find it useful and may have some advice to give.

My really big one is I wish I was less of a 'people pleaser', less compliant.

I think I have been quite easily manipulated during my life and if I hadn't been, my life would have taken a different course.

I have finally learnt to say 'no' and am trying hard to 'please myself'.

What about you?
