When we talk about worship, we must understand how directional it really is; it is our gift to God. It is not something that is for us, or any other thing, it is ONLY for God. Jesus confirms this in Luke 4:8 when He says "You shall worship the Lord your God, and Him only you shall serve."
As worshippers, as lovers of God and stewards of His presence, we need to make every effort to seek out and understand what God desires from us when worship. When bringing a gift to someone, if you were thoughtful, you would consider what this person would want, and then give them something according to their interests. So it is with the worship we bring to Him.
2nd Chronicles 16:9a "For the eyes of the Lord run to and fro throughout the whole earth, to show Himself strong on behalf of those whose heart is loyal to Him."
Acts 13:22 "And when He had removed him (Saul), He raised up for them David as king, to whom also He gave testimony and said, ‘I have found David the son of Jesse,a man after My own heart, who will do all My will.’"
When choosing the second king of Israel, God chose David, the only man whom God testified as being "after His heart," which is to say, David had a heart that is conformed to God's and had a desire to know God. When God looks at the heart of a leader or a worshiper, He is looking for one that can be conformed to His and is looking for someone who wants to know who God is personally, rather than just knowing "about" God.
How does this happen?
