_These are my mistakes, and I hope you won't do the same so you can be more successful here. Right now, I'm only learning with my experience and hopefully I can give something more helpful in the future.
We thank God that you realized your mistakes and share it here for others to learn. According to the saying, "experience is the best teacher". Now that you have experienced the unexperience nature of life, you have learned yours in the forum. Everyone has their experience in the forum. Reading always give wisdom than knowledge. Yes you will give things that more useful and it will be helpful if only you are reading other users thread and learn and write constructively. Once again delayer is not a barrier, wasted time is not a barrier but how focus and seriousness are you now in the forum is the issue.
