Too many people can't decide fast and that's why they can't make a progress, that's why their lives were full of regrets. If a decision is waiting for you, if you need to decide in just one day then decide, never make excuses, never entertain any stupid negative thoughts. Every decision is the right decision if you will not feel regretful about it, every action is the right action for as long as your intention is positive. If you think it will be good for your life then decide that you're going to do it. People who are making fast progress are people who can decide fast. It is what it is, it should happen, even if your decision is wrong... you can still make adjustments, you can still correct it.
No regrets can only be achieved by deciding that you're going to do it. Even if your decision is wrong, at least you found out what will happen. Unlike someone who can't decide, he will always think about what could have happen if he made the decision. To avoid overthinking... just do it even if it is hard, just do it even if it's not making enough results. Decide that you're going to move forward everyday, decide that you're not going to quit even if the road you're travelling is very bumpy and rocky. It's just a matter of perseverance, it's just a matter of making a stand for your decision and not blaming yourself or anybody if something wrong is already showing up.
Making fast decisions is better than thinking for one week or a month or even a year if you're going to do it or not. Your mind will be stressed if you can't make a decision, you have to have a big heart, you have to convince yourself that every decision that you're going to make is right. Perseverance is the only answer to a wrong decision, decide that you're not going to quit no matter what and that wrong decision will look right in the end, you're still in control of your fate even if your decision is wrong granted that you don't give up and do whatever it takes to thrive in life. The reality is you're the one who is controlling your life and not the decisions that you made. You still need to work hard after making a wrong or right decision, you still need to become better everyday. It only means you have nothing to lose whether you made a wrong or right decision because the power is still in your hands, you're still in control no matter what.
Decide that you're going to move to a different house, decide that you're going to leave your job, decide that you're going to start a new business, decide that you're going all in even if you're struggling so bad, decide that you're going to chase your dream, decide that you will leave some of your toxic friends, decide that you're going to do it your way. Never feel that any decision you did was wrong, never feel that your heart is wrong, once you made a decision... be happy that you did it and live by it, never go back, never feel sorry if something wrong is happening, have no regrets and make a stand for your decision, in other words you live and die with it.
