Sometimes a person may have created a budget and he is executing his BTC investment plan, and maybe 6-12 months down the road, he realizes that he made some mistakes in his budget. One of the great things about making a plan is that there likely would be various cushions built into the plan and if mistakes are made, then the mistakes can be addressed along the way in order to make the plan stronger at the later point down the road... versus someone who had not planned very well, then that person gets themselves into a pickle since he had not planned very well and probably did not include any kind of financial and/or psychological cushion in regards to whatever he had been doing...so planning and tweaking along the way are great things for anyone in their earliest years of investing, and it can take a bit of time to really get used to following the plan and adjusting it along the way and reaching various goals along the way, too.
Mistakes are not supposed to be much of a deal to the process, life is full of mistakes/regrets/assuming to have picked a better option but at most how we relieve ourselves matters, when decision making becomes a skill it is the easiest way out from such mistakes. For anyone who has failed to plan, may have already made plans to just rub off the surface of investing, any heat can eventually pull out such a person from his investment plan without a second thought. I suggest anyone to stick with making those plans, accepting mistakes and taking corrections if it does happens, adjusting is better than no planning.
You haven't said anything wrong nor have JayJuanGee said anything except the truth, perhaps I will have to add this; chasing perfection should never be part of the plan of any investor or a yone into bitcoin investment whether newbies or someone who's already deep into it.
Trying to make everything perfect only results in one thing which is not achieving a good goal because basically life is never meant to be simple so every step you take towards achieving great goals like bitcoin investment it will have to throw some stones towards you all you have to do is pick them up and build a shade towards your investment so that nothing can wave you to the extent of wanting to sell your holdings.
Since mistakes is inevitable one should prioritise achieving the slightest amount of bitcoin instead of complaining about ones mistakes or quitting the journey out of regrets. perhaps all have have to do is follow the plans and weigh your budget with your plans if they are compatible enough to carry out as time goes on where changes needs to be made then you can make them yet achieving your bitcoin which is the real deal.
