The Tower urges us to be careful with our wealth - save, invest wisely, don't spend excessively. It also tells us in no uncertain terms that we need to consistently work on stable foundations - that includes the relationships that we feel stand the strongest chance of being there for us when everything goes spectacularly to shit! Sometimes, when we're building high, we forget about what's beneath holding it all up and keeping it together. Being wary of what's likely to go wrong and what we've got to fall back on when our luck changes will give us the best fighting chance of dealing with disaster. Basically, accepting that Sod's Law has its part to play in our lives is healthier than denial. The most important thing to remember is that we can fall back on ourselves in times of trouble. We are the steel rod running through the length of the structure and we shouldn't sell ourselves short on that point. Even when the person we thought we could rely on the most fails to come through, we can be our own source of support. Nothing is ever as bad as it seems.
This card also has something to say about negative thought and behaviour patterns. What do you keep doing time after time that's having a negative effect? What bad habit needs to be stopped before it becomes a lifelong excuse not to realise your potential? Make a start on improving yourself so that you can take greater credit for what goes right as well as responsibility for what goes wrong.
