It's better to study endgames first (beside tactics) because:
- you learn the effectiveness and coordination of your pieces
- you learn to calculate
- you learn how important your pawns are and how to handle them
- you can often score in games when your opponent is ahead if you have better endgame knowledge
- you learn how to play the middlegame in relation to specific endgame situations (where to put your pieces, which pieces to exchange)
- you don't have to look for a winning combination the whole time and don't have to force the win (it often will end badly) because you can easily lead over to the endgame, simplify the position etc.
