I got this idea from the book Liber Null by Peter J. Carroll, so I created my own method.
1.. Make a sentence of your desire. Remember to make it present tense in all capital letters.
I AM EATING BETTER AND HEALTHIER
2. Delete all repeating letters.
M - G - B - D - L -H
3. Now lets get creative! Add vowels and switch around the letters till you get nice sounding magical phrase.
DILAH - GEMBO
4. After choosing your Vowels you can switch them around some more.
ELDA - HOBMIE
5. Now your down!
Unlike other sigils these do not need to be charged at all, You activate them through use and the way you use the are similar to affirmations. Most people would use them for meditation or perhaps making your own mantra for spellwork.
I hoped you enjoyed this method for magick and I wish you the best of luck for your journeys!
