"Inspiration is perishable, use it before its gone" is tweeted by naval I guess. According to me there's a cycle.
Inspiration → Action → momentum → Inspiration and it goes on.
Most people start from inspiration, they tend to start work after watching an motivational video ,by reading some quotes or by listening to someones advice. There's nothing wrong in this approach but we tend to loose the motivation after some time.
people wanting to build habits should know about rewards and incentives. Do check out this wonderful article on Incentives.
To successfully complete our tasks we should start with Action, You might be thinking what Rubbish I am talking as you guys are reading this post as you lack to take action, but here I would like to suggest you guys form some cues to take the original action. for ex- if you want to exercise just change your clothes to the gym wear or wear your shoes. Soon you'll lose resistance to go to the gym.
I just thought to Write the heading of this post but after writing the heading I lost the resistance to write, and hence I'm Writing. But sometimes its okay to start your day by watching a video which gets you pumped up.
I would recommend you guys to read atomic habits by James Clear if you haven't read it yet
