Exactly. Prayer (Namaz/ Salah/ Puja) is just one form of worship. Rememberance of Allah (Dikhr, Tasbeeh, chanting mantras, etc) is another form of worship, but as Teggy has put it so nicely, all other things of how we conduct of lives with the intention of following guidance given by Allah is worship.
Islam is a way of life, it is not compartmentalized for only one day of the week or certain times of the day.
