Mit ernstem und konzentriertem Blick, Brainstorming und Nachdenken über ein herausforderndes Problem - Stockfoto & -bild

Looking concentrated and thinking hard on an idea, imagining a solution to a challenge or problem

Looking concentrated and thinking hard on an idea, imagining a solution to a challenge or problem

Feeling stressed and frustrated, raising hands to head, feeling tired, unhappy and with migraine

Yawning lazily early in the morning, waking and looking sleepy, tired and bored

Greeting the camera with a military salute in an act of honor and patriotism, showing respect

Looking unhappy and stressed, suicide gesture making gun sign with hand, pointing to head

With a serious and concentrated look, brainstorming and thinking about a challenging problem

Yawning lazily early in the morning, waking and looking sleepy, tired and bored

Feeling like a genius holding finger proudly up in the air after realizing a great idea, saying eureka

Pressing lips together with a cute, fun, happy, lovely expression, sending a kiss

Young red head woman looking concentrated and thinking hard on an idea, imagining a solution to a challenge or problem against orange wall

Shouting triumphantly, laughing and feeling happy and excited while celebrating success
