Where did Wemmick get his brooch What dose he mean my guiding star always is get hold of portable property In great expectations?

Wemmick received his brooch as a gift from Miss Skiffins. When he mentions his "guiding star" being to "get hold of portable property," he is emphasizing the importance of financial security and the need to acquire assets that can be easily carried or converted into cash in times of need. This reflects his practical and cautious approach to life, contrasting with his more whimsical and eccentric behavior outside of work.
