If within that meditation I feel like going longer, I don’t fight the feeling and just keep going until I feel complete with it.
Other times up to 5 times a day and for me each sessions about 20-15 minutes
They all count
The length of time and how long you meditate for is completely up to you: you may find to begin with you are only able to manage a couple of minutes, but this will build as you develop your skill. It helps to have a set time for meditation (I often do it just before I go to sleep), so you remember to do it once a day.
If you have been trying meditation for a few months and find it still isn't working for you, I would suggest you either try a different method of meditation (there are lots of suggestions online) or acknowledge meditation isn't for you and try a different calming activity instead.
Basically try meditation whenever and for the length you find suits you. Not the same length and time suits everyone!
Normally the morning one I try and keep short (~5-10 minutes). The night one is a bit longer (~10-20; sometimes 30 if I need it and can stay awake). The afternoon one maybe around 10 minutes.
But, there are days when I simply don’t have time for myself. On these days I am trying to mediate at least once a day for 10minutes.
I meditate about two times a day. In the morning after a healthy breakfast, and at night before sleep. The duration depends on, well; usually about 20 minutes… It actually depends on how I feel before I begin… More thoughts in my head, more time to clear them in meditation…
On the other hand, I do think that it is useful to have an established routine including meditation, especially if you are just starting. It is much easier to meditate when you are calm already, so practising this skill in a part of the day that is not stressful helps to build up to when you are in a situation when you want to calm down. Do not worry if you are finding it really hard to focus to begin with – this is a difficult skill, and if you need there are many videos online to help you.
On more difficult days, I try to find time to meditate whenever I need it; all it requires is around 30 seconds just to focus on yourself and control your breathing. I often use it heading into or out of a stressful situation: maybe you have to present a presentation or just about to have an interview. It also helps with other emotions: such as while it is important to morn a death of a loved one, meditation can help bring you out of despair, and allow you to keep going even in the darkest of times.
Overall it doesn't matter when, where, why or how long you meditate for, everyone is different and will both need and be able to do different amounts. However, meditation is a useful skill and I do recommend trying to do it around once a day, or even once a week if you don't have time.
