Since tonight is a full moon, why not make it a point to send some healing energy to a friend or the world. If you don't want to do anything major because of the Ostara celebrations, why not make some moon water.
Get some nice clean water (ocean water would be great) and put it into a bowl and set it outside tonight. Spend some time meditating on the Moon and all of Her energies tonight. Once you feel happy with your meditation, pour the water into a jar and seal the lid.
Be sure to use this water during the month in any spells that could use an extra energy boost from the Moon.
