>>8746421There's partial truth in this. Your inspiration can fade away quickly.
Overall there's no set time limit or required investment for a person to get inspired or motivated by something. You can see a person, a thing, concept or an idea and feel inspired in as little as a few seconds, which can last for hours, days, weeks, months, years or even the rest of your life. Instead of thinking that your motivation will fade in some amount of time, it's better to capitalize on your feelings NOW. Don't worry about how your motivation will fade, use those uplifting energetic emotions to build something, improve or learn. Maybe you will lose it next day or next week, you have little to no control over it, but there's a chance you will enter a routine and your new activity wont need "life support" from outside inspiration.
Or maybe you will lose it all in 5 days. So what? At worst it will be 5 days spent trying to do something productive. You will try again next time and then next time. Worrying about progresive worst case scenarios is setting yourself up for failure. Nothing lasts and failure will be the same, regardless if you doompost about it or not. Do something for a week first, don't think about 5 years. Then do it for a month. Half a year. Have minor goals that build a road towards a big one. Succeed or learn from your mistake so you could do better next time.
Never waste an opportunity when you're motivated. It helps with the initial growth pain.
