Try disconnecting yourself from the world before you pray Salah.
Put your phone aside, turn off your computer screen, put the book down and just sit there in utter silence for a minute or two.
Wallahi this will help you develop Khushoo (humbleness, tranquility, calmness and serenity) while you pray before your Lord.
Don’t just pray, to get it out of the way.
Pray to experience prayer.
