If you are thinking of doing an astrological chart, I suggest you start with your birth chart. This is the to me id the most important chart and the easiest.
I have found over the years when doing an astrological chart it is best to combine a few different types of astrological views in combination to get the best reading for yourself or others. While most westerns use only the Sun Signs include looking at the Chinese, and Celtic/Druid information as well. This can give you a better idea of where you stand in the Universe and possibly what awaits you and makes you part of who you are.
Remember though the future is not written in stone and your actions and/or words may change what you see on your birth chart. You can also do love charts, financial charts, and other as well. This is a form of divination so if you do a chart except your birth one have a specific question to ask and keep it in your mind when doing a chart for that specific question.
I will also tell you that to do a thorough chart of any kind can be time-consuming and does not need to be completed in one sitting. If you stop and go back to it make your you ask the question exactly the same way every time. When I do a chart say for how my money situation is going to be over the next year I write my original question down and keep it with the papers for the chart I am doing, that way the question never changes until I am done with that specific chart.
I no longer to charts of any kind for anyone but myself and my family, so please do not ask me to. Thank you.
Blessed be dear ones.
