Dear Drikken,

I am kind of confused by your question. Is this a hypothetical question? Or do you have a real-life example you could share, that would perhaps make it clearer? Without having a good understanding of your question, this is the best advice I can give you:

If you were in a situation where you noticed a problem, but you were unable to do anything to change your situation or the problem, and then the problem faded away as the situation passed, then you no longer have a problem. There’s no need to dwell on it. Continuously thinking about old pains and problems that have faded away take us away from the present, and cause us unneeded pain.

Remember that mindfulness does not require us to have a timely solution to all problems. Mindfulness is nonjudgmental, non-evaluative awareness and acceptance. It is also a continuous practice and way of life- rather than something that you can ‘achieve’ if you try hard enough.

The fact that you noticed a problem, and also noticed there was nothing you could do about it immediately, is awareness. I would now turn your focus to acceptance. You may realize that new emotions, thoughts, or insights arise when you remember past problems. You can mindfully be aware of and accept these, also. Letting go, forgiving yourself for less-mindful moments, and returning your mind to present awareness becomes easier with acceptance. This is a continuous practice that will become easier with time and experience.
