I am starting with all in.
How do you start the tournament?
This is totally wrong and true bingo.
Try to sit a little and observe your opponents, it is also good to label them and make small notes as how they play.
Focus on their pre-flop action and bet-sizing...
I try this and it helps me quite a lot.
Out of the 10.000 players i "mostly" end up in the top 15%.
Sometimes you do have bad beats: for example.
you have aa on the bb and utg+2 shoves all-in.
You call and he ha k5 off and hits his two pair and your out, but you can't let that stop you from playing poker the right way.
On the long run you will always be a winner..
Hope this helps a bit..
