There isn't going to a time where it's convenient to worship God. You aren't going to wake up early one day not tired and then read the Bible. You can't wait for a time when you aren't doing anything and then pray to God. You have to make time for You Him, really your whole day should be spent with Him but you should also have times when you just focus on Him. You should spend your time with God so that you can receive His gifts or peace, joy, and love. Jesus didn't die when it was a good time for Him and didn't interfere with what He wanted to do. God isn't with you all the time because He doesn't have anything better to do, it's because He lives you and He wants you to love Him. We should all give up some of our time, like five minutes, daily to sit quietly with God. You can't let yourself make any excuses no matter how busy you are you can spare five minutes for the Lord of the Universe. Also keep Him in your mind the whole day and walk with Him.
