Striving for... what?

Utthita hasta pādāṅguṣṭāsana

I am aware that having started all this while already counting backwards, some asanas are likely to be impossible or very tough.

What I am not willing to accept is me using my age as an excuse and thus get used to the idea of not being able, just to take cover behind the shield of "I will never get there, so what's the point of making all those efforts?"

I’d rather quit my practice right now than start thinking like this.
