Welcome to the community
It seems you have taken a huge first step in self-knowledge, but probably haven't realised it yet.
This particular body/mind phenomenon seems to need constant stimulation in order to feel challenged/satisfied/whole - whatever. It is an addiction, just as potent as an addiction to food, drink, drugs.
This is great fuel for your meditation practice.
Have a go at walking meditation. Choose an object to focus on - the breath, a mantra, sensations in the body, ....
Go somewhere you can have a marker for about twenty paces, like a tree, a stick, a stone, etc. Decide how long you will walk for. Begin by standing still and focusing on your meditation object, then walk and be aware whenever your mind drifts off the object. Turn, stand still, refocus if necessary and walk again.
Your goals can shift as you improve
1) noticing the reduction in 'drifts' in each walk between the marker.
2) If you can walk between the marker without the mind drifting off the meditation object, then notice how many times you can turn before drifting.
3) If you are not drifting for many turns between the markers then notice the thoughts that pop up just to disappear again without developing at all.
This should keep you busy for quite some time!
Of course, this will only feed your need for constant stimulation. It is necessary to start from where you are at, but you also need an antidote.
Have sitting meditation times, too. You can alternate between sitting and walking. In your sitting meditation have the same meditation object as you chose for your walking meditation. I expect you will quickly feel the same boredom as before. Great! Now you can explore this feeling. How do you know you are bored? What is it in this body/mind phenomenon that tells you boredom is present? Does it begin as soon as you sit down? How long before it begins? What are the first signs? How many indicators of boredom are there? Watch carefully in each sit for the very first sign that boredom is beginning.
Good luck! Keep us posted on how you are getting along.
