Nature, Nurture, Personality or luck?

So I sat at a farm yesterday in the sun 🌞🌞with my little lady and some friends and their children watching her eat her lunch 🍊🍏🍞and I realised how "lucky" I am with her and how "good" she actually is 💓💓💓💓.  The more I have thought about it since, the more I have thought, how much of it is nurture, how much is nature - that age old debate, and if any of it is down to luck? It would be arrogant to assume it was nurture as I am definitely no parenting guru and I don't have anyone to compare her to as a mum of one

My daughter first went to the childminders at 11 months of age and I was always told how she would happily have ten like her.  There were very few tears at drop off every morning, she was very accepting and still is of most things.  Lots of people have commented on how calm and easy she is and to be honest she is generally a little doll.  Sure we have had our battles - a nearly 2 year refusal to eat dinner for mummy to the point of tears (mine), but we sailed through the 2s and the 3s with very few tantrums and now we are 4 and she continues to be a really good girl.  The last few days I have had my breakfast poured for me (not necessarily what I would have eaten, but it's the thought😍). Perhaps the lack of tantrums was due to her ability to talk stupidly early.

I can't profess to being a particularly outstanding parent, stroppy, stressed and tired more like 😈 - trying to run a house, set up a business and actually see my treasure will do that to you 😩😩😪.  In the first year of her life we battled reflux accompanied by lots of screaming (not fun), and I had very little support and lots of stress with a very ill mum.  To top that year off I separated from her dad so all in all not a rosy first year 😞. Since then things have continued to be somewhat fraught but I have always had my angel to get me through the hard times 😄😏.  I have always tried to think of her emotions and feelings and given her lots of cuddles and kisses but I have also shouted and lost my temper probably more than I should 😨

I loved my pregnancy and I know we have got a really good attachment, she brings me joy most days 💘💗💙💚💋💋🙌 and I know I am her best friend (for now), but as to her lovely little personality and disposition is this due to luck?  It is the main conclusion I can come to....what do you think?  is personality inate in them from day 1, do we have a great influence in developing or is it all just down to luck?
