It's not uncommon to work with all the elements, infact most people learn to work with them all over a period of time.
Find the element you are most drawn to and start there, once you have learnt to control it and work well with it try working with another element, take your time don't rush into trying to work with them all.
Try learning the Major Arcana card in tarot associated with your sun sign. Rider-Waite/ Crowley's Thoth deck ect.
Research your astrological sun sign(core of each individual)
Zodiac signs are grouped by elements.
Water- try going swimming.
Earth- meditate or go for walks in the park, woods ectra.
Fire- try building a fire (with care of course)
Air- meditate and focus on your breathing.
These are just general suggestions.
Hope this is helpful:)
