Interestingly, I read just today in Yehuda Ahslag's little book "Essence of the Wisdom of Kabbalah" that attainment, hasaga, is the "ultimate degree of understanding" and derives from the phrase "that thy hand shall reach (כי תשיג ידך), meaning that understanding is concrete (in German: be-greifen - grasp). So let's be concrete.
For me, making my own Tree of Life was an important step in learning about the sephiroth. I didn't make it for its beauty but just as study object. Whenever I read something about a sephira or path, I wrote it down on the tree. I used coloured pencils to give some colour to the sephiroth etc.
It's not difficult to make your own Tree of Life. You need a big piece of paper - I always use my old art calendars for such projects, they're made of nice heavy paper.
All you need is a pair of dividers and a bit of patience. You make a circle. On the diameter of this circle, you make another circle. Where the circles meet, you make another circle... You simply add circle after circle, and you see the Flower of Life emerge.
Then you see the dots that belong to the Tree of Life within the Flower of Life once it is big enough. You can emphasize them with smaller circles. And that's you Tree of Life.
Now you can start adding the names of the paths, the sephiroth, additional information... in fact, anything you read or think about the Tree that you don't want to forget. This can become your kabbalah cheat sheet.
I find that when I write something down manually, it's easier to keep it in mind and understand it.
