Ms Marley, I think we pass through at least three stages of ‘maturity’: discarding others’ plans for us; deviating from our own plans for ourselves; & ceasing to plan as though able to anticipate or control unforeseeables.
I do not mean that we should abandon intention, nor work to realise it. I do mean to never stake self-assessment on plans; all are vulnerable.
I am not religious — indeed, am anti-religious — but cherish some of the wisdom & poetry of religious texts (in my case, Christian).
For instance, Matthew 6: Consider the lilies of the field, how they grow; they toil not, neither do they spin: And yet I say unto you, That even Solomon in all his glory was not arrayed like one of these.
Be yourself, today, do your best & be satisfied. If you want more, work toward it but let it come to you (or not).
