Growth towards
what? Growth is generally the result of consistent, applied effort towards something.
If your energy and focus is higher at night, and you sleep away the whole morning (this to me is another topic.. and yes I regularly get home after 12/1am for my work) whatever you do during that time is what you will experience growth in, obviously. Unless of course you are using sleep-hypnosis tracks to reprogram your subconscious and develop skills/attract $$$.
If you look at your life objectively and night life skillset is not truly the #1 thing that needs dealing with (for me it's my work #1, $, health, etc top of that list) then yes. If no, nightlife is not what needs most attention, then this needs re-evaluation. Noone but you can really say what your list 'should' be but deep down most of us know if we're really taking care of biz or not.
If you're just referring to the fact that you have more energy @ night and is that holding you back vs having more in the day, hey man if that's the case what can you do just listen to your body
