This is based on my personal experience! I believe everyone else has gone through something similar. But, just to highlight some stuffs I feel about instinct and how it could always save you from trouble by LISTENING to it. When does your instinct gets stronger, when will it fade?
Instinct, is a complex human behaviour. Have you ever felt very uneasy while leaving your house to work, like something is holding you back and tells you not to go? You ignore the feelings and make yourself feel better by telling yourself it's nothing only to find out that it was meant as a hint or warning for a road disaster that's yet to happen.
Instinct is heavily based on experience! What does a fisherman's instinct says when he sees a school of fishes lying dead by the beach? It triggers a tsunami warning. When someone says you need experience in a field where you work in when you apply for a job, it means that things you pick up by seeing, hearing and doing are as equally important as your theoretical knowledge. In engineering, your logic and intuition should work at its best to make predictions.
So, getting back to what I wanted to discuss. I personally feel instinct helps you to avoid a lot of mess in life, only if you give a chance to your inner voice to rise. Your instinct speaks on almost everything you do and perhaps that's a sign of someone being alive. Your inner voice would tell you what's right and what's wrong. It would suggest you that something isn't going the right way and you may want to double-check on it. When I listen or pay heed to what my instinct says, I was always on the right track and it saves my life most of the time from miseries. There was a point in my life when I was approached by a group of senior girls in my school and I never felt good about them that I instantly knew I would get into trouble if I talk to them any longer. I was right. They were bunch of problematic students!
Your inner voice speaks at different intensity. When you choose to listen to it, it speaks for you all the time and it speaks louder as you decide to search for it. When you ignore it, the voice fades of sooner or later that you feel it doesn't alert you on anything anymore. You tend to do the wrong thing and get swayed from your track. When you get involved in wrong activities, your instinct would instantly alert you that it's not right, you take a second to digest and accept that fact but the next minute when you decide to ignore it, your inner voice fades and it stops giving alerts. You continue having fun in the road taken until something really bad hits you then you wake up from your so-called sweet phase and analyse what went wrong. You realise that you have failed your instinct and hence comes all the mess!
I guess everyone should start analysing what they feel about something and take their time to learn what it tries to imply. If you genuinely feel good about what you are doing, then you are probably on the right track. What does your instinct says now? My instinct says I should stop rambling and get back to work !
