Your first name of Cas has given you energy, drive, and ambition, but also an almost excessively strong-willed and independent nature. It makes you self-sufficient and self-reliant. You often feel you could have achieved even better results. Over-intensity is your challenge; you put a great deal of effort into your activities, but often fail to take time to relax, to view your plans objectively, and perhaps, to consider the opinions of others. Because of the restless qualities within your first name, it is very often difficult for you to find pleasure in ordinary congeniality. Generally, you do not like to waste time on superficial conversation. Your love for others is shown more in your loyalty and sense of fair play rather than in any overt demonstrations of love and affection. You rebel at restrictions and are resourceful in unexpected circumstances. This name spoils relaxation and contentment, the mental qualities necessary for good health. You become intensely involved with everything you plan to do, but the stress arising from frustrating obstacles or misunderstandings with others could prompt you to be intolerant and sarcastic in your expression, with breakdowns in congenial relations with family and friends a possible end result.
