I'm helping younger teammates so much that I sometimes forget my own game

Leadership should support your performance, not replace it. Before the match, decide what your team genuinely needs from you. If one younger midfielder benefits from a few reminders, give them. But you do not need to solve every teammate's positioning while the game is moving. Keep your communication short and then return your attention to your own next action. A useful habit is to ask yourself, 'Where am I in this picture?' after you have helped someone else. You can also share responsibility. Encourage other experienced players to communicate so you are not carrying the whole team socially as well as tactically. Being a leader does not mean becoming the coach on the pitch. Your biggest influence may still be playing your own role well, demanding the ball and setting the standard through your decisions. Help people, but do not disappear from your own game while doing it.
