Is there a point for a not continues practice? i practice for a few years - did basic course and few retreats in Ven/ajhan tong tradition (vipassana)  - But no matter what technique i try (meditating a short amount like 5 minutes - only being mindful - keeping 8 precepts meditating all day) i never manage to keep practicing more than a few days and than taking a break for a few months with 0 minute meditating and being mindful 

Question : I remember reading in several places the importance of continued practice of a steady practice  - and since i make huge breaks all the time and cant seem to prevent them - i wonder if there is a point in the practice if i almost certain i will take this huge breaks  - i don't seem to be "advancing" in any way but i would keep practicing if it was only not seeing "results"  but cause i read in so many place the importance of continued practice   

is there a point in a very inconsistent practice ? if so in what ways  someone who has this an inconsistent practice like mine be advancing advance ?
You should consider the following

Change your approach

In Mahayana Buddhism the emphasis is on skillful means, sitting meditation is not the only practice available, there are plenty of other Dharma practices you can do, build up your base of merits first. You could focus on chanting a particular passage or mantras, this allow your mind something to focus on, and you will naturally see mindful concentration arise through this practice, even without trying to sit.

You could attend services, try to participate in any group chanting if available - Theravada is far as I know is not available for lay people in this case. But there are plenty of Mahayana Buddhist temples that offer group chanting with lay people.

You could offer to help clean up the temple, cleaning is also a powerful practice for mindful concentration if you can focus on what you are doing. Zen monks can do chores like cleaning and still experience Zen also known as Jhana. They blissfully and mindfully perform the tasks needing to be done. Go forth and volunteer! In fact, just participate and enjoy the community, you will learn something!

You can practice offering alms to your community of monks, giving is a great practice of Dāna and give rise to skillful mental qualities. In fact before you try to focus your mind on sitting meditation, try to cultivate positive qualities like love, kindness and avoid negative ones like anger in your daily life.

As you build up your merits, you will find it easier to sit because your mind will naturally begin to calm.

Know that your effort makes a difference

Yes a consistent practice is of course better, but even one single change of thought will make a difference no matter how small. Take comfort in this. Have some confidence in the fact that even when you don't seem to be 'getting somewhere' at least you are not doing something harmful, and that is already making a difference, and if you are not advancing, at least you are not sliding towards more suffering.

And your actions will eventually create the causes and conditions favorable to further your path, whether it will take years or life times. Have some faith.
