Hi, would like to ask for some thought on how to become a senior. Before this i have worked in a mixed role before i actually started to focus back on what i have studied for which is in software. Throughout time, i start to realize that, what i have done previously, didnt get me anywhere near, is it possoble this might be due to one not pushing hard on oneself to learn and grow to become a senior one day? Any thoughts on this is much appreciated.

Senior is just a title. Don't sweat/too obsess over it.
"Real" senior is the role model for his work quality, leadership and his ability to be counted on when issues arise.
Just do your best or beyond your normal job scope and when people started to acknowledge you for your contribution, that indicates that you've progressed to be a 'senior'.
