Need Help

Heyy.. Im 16 years old.. my first question is.. is it good to start surfing at the age of 16????...... When i go to the water .. i start paddling.. and idk why.. i always tend to stand up after the wave had passed.. may be because i dont paddle too much.. and how long should i have to practice my pop-up stance because i surfed today and i coulnd get up not even once..
