Anytime is the perfect time. Any day, you can sit down and make a list of the things that you'd like to focus on, the things that you think would add light to your life, and you can begin that day to move into that new energy.
You are the one who decides. There isn't someone outside of you telling you, "you MUST progress in this EXACT way and if you don't you're a terrible bad person." There's just your own freedom to choose who you want to be and then either alignment with that or not.
